reset - clear all variables of a given name
reset
EXPR
reset
Generally used in a continue block at the end of a loop to clear variables and reset ?? searches so that
they work again. The expression is interpreted as a list of single
characters (hyphens allowed for ranges). All variables and arrays beginning
with one of those letters are reset to their pristine state. If the
expression is omitted, one-match searches (?pattern?) are reset to match
again. Resets only variables or searches in the current package. Always
returns 1. Examples:
reset 'X'; # reset all X variables
reset 'a-z'; # reset lower case variables
reset; # just reset ?? searches
Resetting
``A-Z'' is not recommended because you'll wipe out your
ARGV and
ENV arrays. Resets only package variables--lexical variables are unaffected, but they clean themselves up on scope exit anyway, so you'll probably want to use them instead. See
